System Inspection

Back Up Voltage Inspection
1. Ignition "OFF"
2. Disconnect PCM connector.
3. Ignition "ON"
4. Measure voltage between terminal 6 of the PCM harness connector and chassis ground.
  Specification: Remain stable at battery voltage
5. Are circuits remaining stable at battery voltage?
  YES
  - Using a scan tool, check PCM software version and upgrade as necessary. If version is the newest one, check PCM for contamination, deterioration, or damage. Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NOTE:
  It is necessary to perform the TPS adaptation procedure after the ETC assembly or PCM replacing.
  - TPS adaptation procedure
  Ignition "OFF" and then "ON" without cranking. Wait for 10 seconds under enable conditions.
  → Enable conditions: Battery >10V & Intake Air Temp. >5.3°C(41.5°F) & 5.3°C(41.5°F) < Engine CoolantTemp. <99.8°C(211.6°F)
  NO
